Boxer Miguel Cotto wipes away tears during an interview, Tuesday, Oct. 17, 2017, in New York. Cotto will bid farewell to the ring when he faces Sadam Ali on Dec. 2 in Madison Square Garden _ his “second home,” as he calls it, where he will fight for the 10th and final time of his career.

NEW YORK — The usually stoic Miguel Cotto gets emotional thinking about all the important family moments he missed in two decades as a boxer. Countless hours in the gym, training to become a four-time world champion, kept him away from his wife and four children for weeks and months at a time.

No more after this fight.

Cotto will bid farewell to the ring when he faces Sadam Ali on Dec. 2 in Madison Square Garden — his “second home,” as he calls it, where he will fight for the 10th time to finish his career. After 46 action-packed bouts in four weight classes, the 36-year-old Puerto Rican said he has no regrets about this decision to call it quits, and is looking forward to making up for lost time with his wife Melissa and his children, ages 10 to 21.

“I’ve missed birthdays, graduations … you name it,” a teary Cotto said Tuesday in an interview with The Associated Press. “Those moments are not coming back, but I’ll enjoy each day to the fullest. And now I won’t miss a single day of their lives.”

Cotto recalled a promise he made long ago to retire at 30 years old, one he obviously did not keep. That was almost seven years ago — he turns 37 on Oct. 29 — and since then he fought nine times against big-name opponents like Floyd Mayweather Jr. and Saul “Canelo” Alvarez, two of the losses in his 41-5 record.

Cotto now guarantees there will be no going back on his word, saying he is “150 percent” sure he will hang up the gloves after defending the WBO super welterweight title he won in August against Yoshihiro Kamegai. He said it’s time to give his family the attention it deserves.

“I know they are proud of me, and they are crazy about the idea of having me with them every day,” Cotto said.

Ali, a 29-year-old from Brooklyn, is not a blue-chip opponent like many of the fighters Cotto faced since he made his professional debut in 2001, but the future Hall of Famer knows there is no need to risk much in his send-off.

Still, don’t expect Cotto to change his methodical attacking style for his last hurrah.

“My whole career I brought my best in every opportunity that I had, and I don’t have any plans of changing anything,” he said. “I depart from here to LA to start my training camp, and as always I’m going to give it all.”

Whatever happens on Dec. 2, Cotto’s sparkling resume speaks for itself: In an eight-year span from 2007, he fought all-time greats like Mayweather, Alvarez, Manny Pacquiao, Zab Judah, Shane Mosley and Sergio Martinez, most of them in their prime. Pacquiao, Antonio Margarito and Austin Trout gave him his three other losses.

He won world titles in the super lightweight, welterweight, super welterweight and middleweight divisions. Listed at 5-foot-7, in many cases he faced much bigger opponents as he moved up in weight.

“I’m always here to face the best opponent out there, in every chance, and sometimes the best ones were in higher divisions,” he said, “and I just tried to put myself out there.”

When asked to choose his favorite fight, Cotto did not pick any of the big-ticket bouts. Instead, he said it was his 2005 knockout win in Atlantic City over little-known Ricardo Torres of Colombia.

That was his 25th fight, and for the first time in his career, Cotto went down in the second round.

“That was the fight that made Miguel Cotto the boxer he is right now,” Cotto said. “In this fight I learned that you have to pass through difficult moments in your life to get whatever you want in life.”

Cotto said he plans to maintain ties with boxing through his promotion company in Puerto Rico, where he also wants to help in the recovery process after the devastating Hurricane Maria.

But his main goal will be to become a full-time parent and husband.

“My children have never sat down with me to ask me for explanations,” he said. “I’ve never sat down with them to explain all the sacrifices I’ve made in life so they can be where they are. When those questions come, I’ve got an answer for each and every one of them.”

DAZN will broadcast a boxing match between YouTube stars Logan Paul and KSI this fall. The fight, scheduled for Nov. 9, will take place at Staples Center in Los Angeles and will be a rematch of a bout between the two Internet celebrities that aired on YouTube pay-per-view last August.
